Accepted Answer

To update a blob's metadata without losing its existing metadata, the application must follow these steps:
1. **FetchAttributesAsync:** Retrieve the blob's system properties and user-defined metadata from the service. This populates the local `Metadata` collection.
2. **Metadata.Add:** Add or modify the metadata key-value pairs in the local `Metadata` collection.
3. **SetMetadataAsync:** Write the local metadata collection back to the blob on the Azure Storage service.
